crenulately-serrulatc, petiolate, opposite, remote, patent, 
slightly unequal at base, upper half largest, margin incras- 
sated, revolute, \\ — 2.f inches long, 4—6 lines wide: termi¬ 
nal pinnule , very long, acuminate, serrate, 3J— 5b inches: 
veins , pinnate, opposite, simple, rarely forked. Sori , linear, 
thick, distichous, confined to upper pinnae, intra-marginal. 
Involucre , vaulted, glossy, slightly wrinkled, membranaceous 
at margin, brown-red, black at base. Kachis , slightly mar¬

inches, somewhat succulent, blackish-green. 
Ilab. In ravines and dells among scoriae, on the dry vol¬ 
canic range of hills near Manukau Bay; 1842. 
Obs. In affinity this species of Asplenium approaches 
very near to A . obliquum , Forst., from which, however, it 
may at first sight be known, by its being a much smaller 
plant with narrower pinnae. That species is, moreover, de¬ 
scribed as possessing pinnules £< acutis basi oblique cuneatis 
obtuse serratis utrinque striatis.” I have never yet detected 
A. obliquum in any of my wanderings. A. Richard con¬ 
siders it as identical with A . Ivcidum , Forst . ; yet, A. Cun¬ 
ningham states, his having met with it <c in dense forests at 
Wangaroa.”— Vide, Comp. Bot. May., vol. 2, p. 364.
